The difference between moisture-resistant drywall and regular drywall. What is the difference between moisture-resistant drywall and regular drywall?

The construction market offers a variety of materials that can be used for finishing various surfaces, as well as their alignment. Drywall is especially popular. Sheets of this material are quite versatile in use and have many advantages. Also among its varieties you can find moisture-resistant drywall. The characteristics of such material are worth considering in more detail.

Properties of drywall

The waterproof type of material has the same characteristics and physical properties same as regular gypsum board panels. The sheets have the same geometry, so you do not need to select special parts and profiles to install them. Thanks to this, install plasterboard sheets possible using dry special technology.

The main advantages of covering various surfaces with plasterboard sheets are their light weight, ease of processing, high environmental friendliness and a variety of design possibilities. Standard dimensions of the material make it easy to calculate the weight and price of the panels. The thickness of the sheets varies from 8 to 24 mm. The length can reach 4.8 m and the width - 1.3 m.

Before the purchase moisture-resistant plasterboard You should take a closer look at its parameters. The material has the following physical characteristics:

  • Hue.
  • The leaves are usually colored light green. Pink panels may also be sold. This is necessary to distinguish moisture-resistant drywall from regular drywall. Gypsum layer. It contains special chemical substances
  • , giving the material moisture-repellent properties. Each component of the material is completely safe for health. Features of production. Moisture-resistant plasterboard is manufactured according to special technology
  • , which eliminates the development of fungi and mold on the material. Thanks to this property, drywall can be used in basements where there is high humidity.

The dimensions of drywall are selected depending on the purpose of use. You can order sheets of different lengths, but having the same thickness. The minimum value is 7 mm, the maximum is 24 mm. For example, moisture-resistant plasterboard produced by the Knauf company has a thickness of 12 mm. It is installed both in the bathroom and kitchen, as well as in other unheated rooms.

Due to the high flexibility of the hydrophobic material, various shaped elements can be easily created. It will not break even if the panel is bent strongly enough. Thanks to these properties, moisture-resistant gypsum board has gained wide popularity.

Appearance and selection of sheets

Among gypsum plasterboard systems, materials produced by Knauf are especially popular. Despite the fact that moisture-resistant drywall perfectly protects surfaces from moisture, it itself requires additional waterproofing. However, compared to conventional drywall, it will last much longer in areas such as the bathroom.

How to determine the differences between sheets placed on shelves hardware store to choose the most suitable material? Most sheets have standard dimensions and can be designated by an abbreviation:

  • GKLV;
  • KGLO.

The final letters “B” and “O” indicate moisture resistance and fire resistance, respectively. Drywall usually has a different color on each side. One is different brown tint, and the second is green.

Moisture-resistant sheets are impregnated with antifungal and water-resistant compounds. This ensures the safety of the material in conditions high humidity. Such additives can increase the service life of the material. Also, moisture-resistant drywall weighs about 3 kg more than a regular sheet.

The inner side of the panels is attached directly to the sheathing or directly to the walls of the bathroom, kitchen and toilet. External side sheets must be protected with a special primer or water-repellent paint. Also, polyvinyl chloride or ceramic tiles, laid on top. Moisture-proof films are successfully used.

Terms of Use

Each panel has profiles on the edges. This allows you to seal the joints between sheets using different materials.

The edges can have the following profiles:

  • rectangular - in this case, sealing of joints is not provided;
  • step contour- intended for reinforcement tape and gypsum putty;
  • rounded - the joints are sealed with putty without the use of reinforced tape.

When laying the panels, you should make sure that the chamfered part is on the outside. For standard sheets it is lighter. The same rule applies to moisture-resistant drywall. Such material can be used for the same purposes as regular material, but this condition does not work in reverse.

The cost of moisture-resistant drywall is slightly higher than regular drywall. It is also purchased only for use in certain conditions. For these reasons buy moisture resistant material, to decorate rooms for which a regular one would be quite suitable, is impractical. It is worth paying attention to the device proper ventilation premises. It is necessary for the full release of moisture that has been accumulated by plasterboard sheets.

Obviously, moisture-resistant drywall can be used for most types of finishing works. It is laid on the ceiling and walls, as well as on prefabricated partitions. The universal material is characterized by increased practicality and excellent appearance.

Application area

Thanks to many positive characteristics material it can be used for finishing suspended ceilings and wall repairs. Drywall also serves the purpose of leveling wall surfaces.

In addition, moisture-resistant material can be used as a passive measure to protect against the spread of fire. Such sheets are used for internal and external works. Moisture-resistant panels can also be washed. If you have a choice between ordinary and moisture-resistant sheets for finishing the kitchen, you should pay attention to the second option. The cost of materials will vary, but in terms of service life, moisture-resistant drywall is significantly superior to its simple “brother.”

Laying methods

Installation of plasterboard sheets can be done in several ways. Frame - it is followed when the walls have many irregularities. In this case, the drywall is mounted on a pre-made metal sheathing. The latter is created from galvanized profiles. Fasten the frame to the wall with dowels or self-tapping screws.

Important! Moisture-resistant plasterboard should not be laid on wood sheathing if it must be used in a damp room.

To perform the lathing, you can use a metal profile of the following dimensions:

  • W - large profile, which is used to create a general wall frame;
  • D - it is used for interior work.

Guides are produced U-shaped. They have a smooth surface. Also, to install drywall you will need a support profile, which is distinguished by the presence of ribbed walls.

In order to level the walls, you can use the second method of attaching sheets of moisture-resistant drywall - with glue. This method is characterized by greater simplicity and high installation speed. When choosing this method, an adhesive mixture is simply applied to sheets of material, and then the plate is pressed tightly against the wall.

If the walls have unevenness less than 4 mm, the plasterboard can be fixed using putty. At large sizes For depressions or protrusions, Perlfix glue must be used.

Work stages

When choosing frame method several successive steps must be completed. On each of them you need to pay attention Special attention correctness of work. Frame method Installation of drywall is carried out in this way:

  • Markings are applied for each part of the frame.
  • A sealing tape must be glued to the guide profile adjacent to the ceiling surface.
  • Secure the guides using self-tapping screws. Fastening is carried out in increments of 10 cm.
  • Using a plumb line, it is necessary to mark the racks. It is also worth considering that they are placed 60 cm from each other. The racks are fastened with rivets.
  • Humo-insulating material is placed in the cavity of the frame. Also at this stage, electrical wiring is carried out - it must be placed in a corrugated pipe.
  • All communications are securely secured.
  • It is worthwhile to provide holes in the drywall for switches and sockets. After this, each panel is pressed tightly against the frame and secured with self-tapping screws 25 mm long. A distance of 25 cm must be left between them.
  • The seams are sealed with putty, and then the entire surface is treated with a moisture-resistant primer.

After this, the installation of sockets and switches is carried out. Now you can apply paint or lay tiles to the surface.

When attaching drywall to glue, you should also follow a certain sequence:

  • Clean the base, remove old finishing. Determine the presence of irregularities.
  • Large tubercles are knocked down using a puncher.
  • After this, the wall is marked.
  • A primer is applied to the surface for better adhesion to the finishing material.
  • Cut out sheets of drywall in accordance with the locations of sockets and switches. The canvases are cut so that approximately 10 mm remains between the sheathing and the floor. This gap is made to provide air access to the glue. After finishing the work, it is sealed with sealant.
  • Sheets of plasterboard are laid on wooden slats.
  • Glue is applied in small slides. Their diameter should be approximately 100 mm and height 25 mm. A distance of 20-30 cm should be left between the slides.
  • To control the height of the lower gap, wooden wedges must be attached to the wall from below.
  • A sheet of moisture-resistant plasterboard must be applied to the wall, level the sheet along the plane, and then horizontally and vertically. Finishing starts from the corner.

Advice! Before installation, the panels must be left in the room where finishing will be carried out for at least two days. This is necessary so that the sheets do not become deformed.

After the work is completed, the glue should be allowed to dry completely. The seams must be taped with reinforcing tape and then puttied. Wedges are removed from the bottom gap, and the space is filled with silicone or acrylic sealant.

Drywall is a durable and easy-to-use material that can be used, among other things, wet areas. What features does moisture-resistant drywall have?

Technical characteristics of moisture-resistant plasterboard

A standard plasterboard sheet consists of three layers - a layer of gypsum is located in the core, and sheets of durable cardboard cover it on top and bottom.

Gypsum is a material prone to crumbling, so cardboard protects it from mechanical destruction. Are looking for

green color

It is not difficult to distinguish the moisture-resistant version of plasterboard boards - according to the accepted standard, they are made in green color, so that there is less chance of confusion. However, both of these materials have low resistance to moisture. Therefore, for a long time, gypsum board was used only in rooms with normal humidity. With its help they performed internal partitions

and ceilings, strengthened floors and walls. It was believed that it was pointless to use drywall in the kitchen, and especially in the bathroom, since constant contact with moist air and steam would quickly deteriorate the material. All this really applies to regular drywall. But on the construction market there is also a moisture-resistant variety, also called GKLV. In its structure, this material is almost identical to the standard one - however, both the gypsum layer and two cardboard sheets are treated with special moisture-resistant impregnations that improve performance characteristics

GKL.

  • What are the technical characteristics of moisture-resistant plasterboard? Material resistance high humidity
  • Sheet thickness can range from 6.5 millimeters to 24 millimeters.
  • A standard sheet of moisture-resistant plasterboard in length and width ranges from 600 by 2000 millimeters to 1200 by 4000 millimeters.
  • Moisture-resistant gypsum board is quite resistant to fire - such drywall belongs to group G1, ignites slowly, does not form large quantity smoke and emits few toxic substances.
  • The material is suitable for both dry and wet cleaning.

It is very easy to distinguish a moisture-resistant type of gypsum plasterboard from a regular one. Firstly, there is always appropriate marking on the packaging, explaining in what conditions the gypsum board sheet can be used. And secondly, moisture-resistant material almost always has green or light green color surfaces - whereas regular drywall Available in grey.


Where can GKLV be used?

What is the main advantage of moisture-resistant plasterboard sheet? Of course, the scope of its application is expanding significantly. This material can be used for almost any purpose - without regard to the level of humidity in the room.

GKLV is used to carry out ordinary work- making walls and partitions, creating multi-level ceilings. Thanks to him they are expanding design possibilities

for the kitchen - here you can also make a ceiling with height differences, without fear that the main material will become unusable from damp fumes. And of course, Moisture-resistant plasterboard remains especially in demand in bathrooms. Ceilings are made from it, walls are sheathed with it, gypsum board is used in small jobs

- for example, when creating a closed niche under the bathroom. GKLV's resistance to water makes it a durable and inexpensive option. But of course, we must not forget about one thing important point

. Even moisture-resistant drywall cannot show the same resistance to water as, say, tile. In direct contact with moisture, it will still deteriorate - albeit very slowly. In order to keep the material in good condition , it must be additionally protected from moisture. For example, drywall can be painted with moisture-resistant paint, closed vinyl wallpaper or plastic panels . You should also ventilate the kitchen and bathroom more often and monitor quality work

exhaust system.

Drywall Knauf - brand features different manufacturers may vary in quality. Practical resistance to moisture depends on many aspects - on the quality of raw materials, on compliance with all rules during manufacturing, on the moisture-resistant impregnations used.


The greatest demand in Russia is for GKLV from German company Knauf. KNAUF plasterboard has some features that set it apart from its competitors.

  • The material retains all its properties at humidity levels up to 90%.
  • The gypsum core and cardboard layers are treated with high-quality hydrophobic impregnations.
  • Drywall is resistant to mechanical stress- you don’t have to worry about damaging it with an accidental blow.
  • GKLV easily tolerates accidental direct exposure to moisture.
  • Knauf products are environmentally friendly clean materials, in the production of which no toxic chemicals are used. In particular, natural starch plays the role of a binding composition here.
  • Moisture resistant material from German manufacturer has good fire-resistant properties. Such drywall does not burn at all, but only chars when exposed to high temperatures for a long time.

The Knauf company produces plasterboard sheets of all common dimensions, so for any purpose you can find a suitable material among the product line. If necessary, Knauf can be easily processed and brought to the desired size.

Knauf is a quality proven over the years. It is also worth noting that the German company produces many other building materials, perfectly combined with each other. Thus, if during repairs you use, for example, adhesives from Knauf, it would be wise to choose drywall from this brand - there is no doubt that when working, the two materials will fit together and will not complicate the repair.

Cost of moisture-resistant drywall

How much does moisture-resistant drywall cost? Its price is quite low - about 200 - 250 rubles per sheet.


Of course, when carrying out repairs, quite a lot of material will be required. To understand exactly how much it will cost to buy drywall, you need to measure the dimensions of the room and calculate how many sheets will be needed for the job. Also keep in mind that some amount of material will inevitably be damaged - even experienced repairmen make mistakes. As a rule, it is customary to buy materials with a reserve of approximately 10 - 15% - this way you get a guarantee that even with a significant amount of defective drywall there will be enough for all the planned work.

Gkl is one of the most universal materials For interior decoration in residential and non-residential premises. It is used for cladding walls, erecting partitions, creating complex elements and multi-level ceilings. But the standard sheet has a drawback - destruction when exposed to large amounts of moisture. Therefore, for bathrooms and wall cladding around window openings moisture-resistant plasterboard is used. It is somewhat different in its structure and composition from regular gypsum board and is suitable for use in rooms with high humidity.

Technical characteristics of GKLV

Waterproof drywall consists of a gypsum core with hydrophobic additives and two layers of treated cardboard special compounds. These components perform the functions of protection against moisture and fungus formation and may differ in their formulation depending on the manufacturer.

For maximum effect It is recommended to use moisture-resistant plasterboard only in well-ventilated and ventilated areas. In addition, you should pay attention to the labeling. Sheets are divided into two groups depending on the number of surface defects (A or B). It is known that the smoother the surface, the better the surface layer (putty) will adhere to it. Hence, similar design(type A) will be more durable, although less affordable.

What is the visual difference between moisture-resistant drywall and regular drywall? First of all, by color. The majority of manufacturers (for example, Knauf) offer green or light green leaf, but sometimes pink-tinged material is also found.

There are two types of moisture-resistant sheet:

  • GKLV (moisture resistant);
  • gklvo (moisture-resistant and fire-resistant).

The dimensions of moisture-resistant plasterboard sheets are always standard: from 600x2000 mm to 1200x4000 mm. The first number corresponds to the width of the sheet, and the second to the length. The pitch is usually 50 mm.

In addition, gypsum boards may vary in thickness. The range of values ​​is from 6.5 to 24 mm. Its choice always depends on the operating conditions and purpose. For example, to build walls in apartments, they take a sheet with a thickness of at least 12.5 mm, but to create arches and figures, waterproof plasterboard with a transverse dimension of 6.5 to 12.5 mm is suitable.

In addition, a high-quality sheet always has markings. It includes a number the most important characteristics, such as:

  • leaf type;
  • group(type);
  • type of edge (straight, thinned, semi-circular, semi-circular and thinned, rounded);
  • dimensions;
  • reference to standard.

Features of use

Before upholstering your bathroom, you need to remember one fact: even the most quality material does not have moisture resistance above 80-85%. Therefore, treating with moisture-resistant paint or laying tiles on the surface of the sheet will not be superfluous.

Otherwise, drywall has undeniable advantages over other materials. It is safe for health, easy to install, affordable, does not require special care and makes it possible to implement any design solutions. For example, using moisture-resistant plasterboard of small thickness, you can decorate the bathroom with an interesting designer ceiling with elements marine theme(in waves).

In addition to moisture-resistant and fire-resistant sheets, builders often use gypsum fiber sheets. In terms of its characteristics, it surpasses standard materials due to its special structure. Gypsum fiber can also be moisture resistant, while it has high mechanical strength and thermal insulation, and does not crumble when cut. Therefore, it is advisable to level the walls using gvl, but to create figured elements and arches the best option will become gkl.

The process of installing moisture-resistant drywall

Installation process waterproof drywall practically no different from installing a gypsum board sheet of the same size. Here it is also necessary to install a metal frame made of guides and rack profiles. To do this you will need a certain set of tools and components. Self-tapping screws, dowels, profiles, tools for marking and drilling holes - all this should be purchased. In addition, you need plasterboard sheets, which will cost a little more than standard plasterboards.

There are several nuances of installation in a damp room:

  • normal ventilation must be ensured during all work;
  • step between metal parts the grating should be smaller than usual;
  • Only aluminum can be used as a frame; wood will have to be abandoned;
  • the seams must be carefully sealed.

Many novice builders cannot find the answer to which side to mount moisture-resistant drywall. And the answer is simple: it all depends on the location of the groove, which appears when the end is positioned at a certain angle. The color of the sheet doesn't matter here.

For installation, you need self-tapping screws, which are attached at a distance of about 20 cm. It is necessary to leave gaps small size between the joints of moisture-resistant drywall. This will ensure high-quality processing putty the entire surface. The putty is repeated again after priming. Then you can begin finishing with special waterproof materials.

That's it, the process of installing waterproof drywall is over. It is not as complicated as it seems, but it has a number of nuances and requires a lot of patience. After all, any humid environment reduces the service life of the quality repairs. That's why it's so important to ensure good forced ventilation and take the little things seriously.

In the construction of houses and renovation of premises, environmental sheets made of gypsum filler, externally limited by layers of cardboard, are becoming increasingly popular. The use of gypsum sheets has become an alternative to plaster. The scope of application depends on the type of building material. Use drywall as interior partitions, for creating complex configuration ceilings, walls. Moisture-resistant drywall - a solution for uneven walls in the bathroom and rooms where there is dampness.

Composition and properties

The building material consists of 93% gypsum and 6% cardboard. The remaining one percent is starch, moisture and surfactants. The only flammable component is the cardboard layer, and if a fire occurs, it does not ignite, but smolders due to the lack of air between the layers. Moisture-resistant drywall is pliable. Once the material is wet, it becomes possible to give it a semicircular shape of different diameters.

The sheets are attached to the lathing (it is more popular to use metal profiles) or to mastic. By erecting structures using plasterboard, you can achieve sound insulation. It all depends on the thickness of the material, the number of sheets and the depth of the frame. To increase insulation in combination with gypsum material use polystyrene foam or mineral wool.

The most common moisture-resistant plasterboard is “Knauf”. The name comes from the surname of the brothers who created a company producing building materials in Germany. Today, the company’s product range is huge, and the company’s facilities exist in Russia, Ukraine and almost all of Europe.

Types

Depending on the technical characteristics and scope of application, the following types are distinguished:

  • ordinary drywall;
  • fire resistant;
  • moisture and fire resistant;
  • plasterboard is moisture resistant.

The price depends on the type and type of material. The moisture-resistant sheet has a distinctive green color with blue lettering. The reduced ability of the material to absorb moisture is due to the presence of special additives in the mineral and impregnation of the cardboard with bactericidal antiseptics. The standard width of such sheets is 1.2 m, but the length is 2; 2.5 or 3 m. Thickness of moisture-resistant sheets: 9.5 or 12.5.

Moisture- and fire-resistant sheets are also green, but the inscriptions are written in red.

Marking

The information on the sheet in the form of symbols conveys to the consumer:

  • Name normative document, on which the material was released;
  • sheet dimensions;
  • type of end edge;
  • group;
  • marking by type (for example, GKL - regular type; GKLV - moisture-resistant drywall).

The scope of its application depends on the thickness of the drywall. Sheets of medium and large thickness (9.5 and 12.5 mm) are intended for finishing walls and ceilings. For structures that require changing the shape of the sheet, arched material with a thickness of 6.5 mm is used.

Based on the shape of the end, there are 5 types of sheets with an edge: rounded, straight, semicircular, thinned, and a combination of the last two.

Moisture-resistant plasterboard: characteristics

The finishing material must meet the requirements of the state standard, according to which VLGK has the following characteristics.

1. Dimensions:

  • length - 2000; 2500; 3000 mm;
  • thickness - 9.5 and 12.5 mm;
  • width - 1200 mm.

2. External color - green.

3. Marking - blue.

4. Standard - GOST 6266-97.

5. Longitudinal edges - straight, thinned and semicircular with a thinned end.

6. Weight 1 m 2 - 10 kg.

Marking example: GKLV-A-PK 2500 x 1200 x 12.5 GOST6266-97. This is standard moisture-resistant plasterboard - 12.5 mm thick, with straight edges that do not require sealing joints during installation. The letter “A”, according to the standard, denotes a material group in terms of manufacturing accuracy and appearance. There are two groups in total: A and B.

GKLV price for thickness:

  • 8 mm is approximately 260 rubles per sheet;
  • 9 mm - 270 rub.;
  • 12.5 mm - 300 rub.

Application

A cheaper way to finish walls compared to plastering is to cover them with plasterboard. The low cost of materials, low labor costs and ease of installation make this material attractive for both customers and contractors. When remodeling or new construction, there is no need to erect brick interior partitions; the design is sufficient metal frame and drywall. After processing the joints and priming, gypsum plasterboard walls can be covered with any material: paint, wallpaper, tiles.

In the bathroom, kitchen, glazed balcony - in all rooms with inherent dampness, moisture-resistant plasterboard is provided (its price is slightly higher than usual). With the availability of the material, a number of advantages of its use have appeared: no plastering process; ability to hide communications and defects load-bearing walls, ceilings; emergence of new design solutions and the ease of their implementation (columns, niches, figured ceilings).

Thanks to gypsum sheets we get smooth walls and the ceiling, and this is the key to high-quality cladding and neat appearance premises. The material is non-toxic and suitable for residential premises.

It is better to install gypsum boards when all the “wet” work is completed and the clean floor has not yet been installed. If in winter period If you plan to work with the material, then their installation can be carried out in the presence of heating in the room and a temperature of at least 10 degrees. After purchase, it is not recommended to install the slabs; you must leave the material in the room in which it will be used for several days. If there are straight ends, preliminary chamfering of 1/3 of the thickness will be required.

In terms of functionality, buyers and craftsmen have no complaints about the material. Moisture-resistant drywall has no serious drawbacks. The only thing is that it is difficult to use in rooms where it is necessary to save space, since during installation a useful part of the room is taken away. Here you can argue whether it is a lack of material or the Soviet housing layout.

Technologies for the production of building materials are constantly being improved. Manufacturers try to take into account all market needs, external and internal lining are acquiring more and more useful technical characteristics.

GCR has been used in interior decoration for no more than fifteen years, and companies annually offer us improved versions of this universal type finishing of premises. How does moisture-resistant drywall differ from conventional plasterboard, and what new properties and characteristics has it acquired?

Specifications

Cut of gypsum plasterboard, resistant to moisture

The difference between moisture-resistant drywall and conventional plasterboard lies in the production technology and technical characteristics.

The production process consists of forming a flat continuous strip 1200 millimeters wide and different sections. Plasterboard moisture resistant sheets consist of two outer layers of cardboard with a core made of gypsum dough with reinforcing additives.

Moisture resistance of gypsum boards is achieved by treating the outer layer with special water-repellent and antifungal compounds. The composition of the water-repellent mixture is the know-how of each manufacturer and is therefore not disclosed.

Important. Moisture-resistant plasterboard sheet is used for finishing rooms with high humidity, which are provided with constant exhaust ventilation. The manufacturer guarantees moisture resistance when protecting the surface with waterproof primers or moisture-resistant polyvinyl chloride coatings.

Material markings and dimensions

This type of cladding allows you to create a wide variety of geometric designs

According to GOST 6266-97, moisture-resistant plasterboard sheets are divided into two groups according to the number of permissible defects per certain length - “A” and “B”. Of course, it is better to purchase gypsum boards of group “A”, this cladding is different best quality, but at a slightly higher price.

Many buyers ask the question - how to distinguish moisture-resistant gypsum plasterboard from regular one? Of course, you need to study the technical documentation. But you can also determine by coloring which gypsum board is resistant to moisture.

Moisture-resistant wall plasterboard is always painted green or light green; some manufacturers offer plasterboard painted in pink color. It depends on the manufacturer.

Moisture-resistant plasterboard sheets are marked with the following abbreviations:

  • GKLV– a moisture-resistant finishing option used in rooms with high air humidity, provided with an exhaust ventilation system;
  • GKLVOfinishing material, resistant to high humidity, with increased resistance to open flame.

Sheet sizes depend on the surface being coated

Facing gypsum board is available in the following standard sizes:

  • Length from 2000 mm to 4000 mm in increments of 50 millimeters;
  • Width – 600 and 1200 millimeters;
  • The thickness of moisture-resistant gypsum board depends on the manufacturer and may have following sizes- 6.5 - 8.0 - 12.5 - 14.0 - 16.0 - 18.0 - 29.0 - 24.0 millimeters. It is worth noting that optimal thickness GKL for finishing residential premises - from 12 mm and above;
  • Also, in agreement with the customer, the manufacturer can form the cladding the right size, for example, small-format drywall. This type of gypsum board is very often used for finishing small bathrooms and bathrooms.

Facing tiles on a gypsum plasterboard box

Important. Before purchasing finishing materials, you need to calculate in advance the consumption of finishing and the dimensions of the surfaces to be coated. This will help reduce the cost of repairs.

After all, installation of moisture-resistant drywall is carried out on surfaces of different sizes. Therefore, it is advisable to calculate in advance required amount sheets different sizes so that there is less waste.

For example, the Leroy Merlin supermarket offers a wide selection of finishing materials of all sizes, so you can always choose the ones you need.

GKL edge type

Options for gypsum board edges

The quality and beauty of the cladding largely depends on what type of edge was chosen. This is especially important if the repair is done by yourself, without the involvement of professionals. Although the price for some cladding options with a longitudinal edge convenient for installation is slightly higher, this makes installation much easier.

Based on the type of longitudinal edge, gypsum boards are divided into the following types:

  • PC – straight edge. GKL is intended for dry installation, without sealing joints;
  • UK – thinned edge. The installation instructions provide for puttying the joints using reinforcing tape. For example, the Volma company offers high-quality finishing materials with this type of edge at a very competitive price;
  • PLC – Semicircular edge surface on the face of the sheet. Allows you to putty joints without using reinforcing tape;
  • PLUK - A semicircular edge thinned on the front side, which allows you to putty joints, both with and without the use of reinforcing tape;
  • ZK - a rounded edge surface, involves installation of cladding followed by starting and finishing plaster.

Important. Since the end edges have rectangular shape, then when joining seams it is necessary to chamfer them by 1/3 of the sheet thickness.

Properties and installation features of moisture-resistant plasterboard

Bathroom tiled with moisture-resistant plasterboard

Since the use of moisture-resistant plasterboard most often takes place in bathrooms, bathrooms and kitchens, it has the following properties:

  • Environmental safety. The manufacturer must indicate in technical documentation that no chemical components harmful to human health were used in the production process;
  • Manufacturers are constantly improving production technologies and introducing know-how, solving the problem of how to make drywall one hundred percent moisture resistant. But so far, unfortunately, the moisture resistance of this type of finish does not exceed eighty-five percent;

Kitchen tiling

Important. Even trusting verified large manufacturers It is advisable to additionally treat the cladding with water-repellent paint or a special waterproof plaster mixture.

Is it possible to glue tiles to this type of finish? Of course yes. This will additionally protect the cladding from dampness and mold.

  • Has high strength and wear resistance;
  • The cladding is easy to install and can easily be done by hand;
  • The material makes it possible to create structures of various shapes;
  • The smooth surface allows you to decorate the finish with a variety of finishing materials;
  • Increases heat and sound insulation in the room;
  • Since this finishing material is able to “breathe,” this creates a favorable microclimate in the living space.
